Mine Environmental Engineering
It is the luminous flux on a small surface normal to that direction, divided by the
solid angle (steradians) which the surface subtends at the source of light.
Mathematically, a solid angle must have a point as its apex, and the definition of
luminous ...

A 60 W incandescent light bulb has a luminous flux of 1000 lm. Assume that light
is emitted isotropically from the bulb. (a) What is the luminous efficiency (i.e. the
number of lumens emitted per watt of electrical input power) of the light bulb?
